The paper deals with the industrial experiment works carried out in Kazakhstan on the injection of pseudoplastic polymer nanosystem for reducing production watercut in the oil field with high viscous oil with 80-90 % watercut and low oil recovery rate. The estimation of efficiency justified that during ten months after industrial experiment works conducted, technological effect was more than 100 t of oil for 1 t of injected dry polymer, and the increase of oil recovery rate was 2 % while watercut decreased for 20 %.
